Temperature Altering Garment and Methods of Use Thereon
Human clothing has inner and outer flexible layers that define a space sufficiently large to position a thermal transfer element in any of multiple, non-overlapping positions. The space and the thermal transfer element preferably have cooperating sides of a hook-and-loop attachment. All suitable items of clothing are contemplated, but especially a shirt, jacket or pants that appear to others as a substantially normal garment. Each space has one or more openings, in either the inner or outer layers, and preferably at the shoulders or sides of the torso, or at the pocket areas of pants. The spaces are preferably large, not only relative to the size of a corresponding thermal transfer element, but also to the size of the garment. Thermal transfer elements are preferably disposed in pouches having a thermal insulation on that side, and have only a very thin, thermally transmissive, fabric on the other side.
This application is a continuation of U.S. utility application Ser. No. 11/804,552 filed May 18, 2007, which claims priority to U.S. provisional application No. 60/838,666 filed Aug. 17, 2006.
FIELD OF THE INVENTIONThe field of the invention is clothing that accommodates heating and cooling pads.
BACKGROUNDIt is known to heat or cool parts of the human body to prevent or treat injuries, relieve pain, improve flexibility, warm a person in a cold environment, cool a person in a hot environment, and so forth. A common method for heating or cooling a body part is to contact the part with a hot or cold pack, generically referred herein as a thermal transfer element.
There are many well known methods for applying thermal transfer elements to human body parts. One method is to manually hold a thermal transfer element in contact with a body part that is intended to be heated or cooled. This method has significant disadvantages. First, a person must engage the assistance of another in order to apply a thermal transfer element to a hard-to-reach area. Additionally, a person cannot alone simultaneously apply thermal transfer elements to more than a few areas on the body, since a person is only able to use two hands to hold the packs in place. Finally, because the hands of a person using this method will be occupied, the person will be unable to simultaneously engage in other activities that require use of the hands.
Another method for applying a thermal transfer element to a body part is to physically attach the pack to the body part. Straps, wraps, adhesives, and other means have all been used for that purpose, but all still have several disadvantages. First, the person's movement can be restricted by attachment of thermal transfer elements to certain commonly treated parts, such as the knee. Additionally, a user is likely to find it cumbersome to hold the pack in place with one hand while simultaneously trying to use a strap or other means to secure the pack in place. Furthermore, attaching a thermal transfer element too tightly can impede circulation and cause tissue damage by disrupting blood flow through the treated body part. Finally, it is difficult to physically attach a thermal transfer element to certain body parts, such as the back, without engaging the assistance of another.
Many devices and methods have been developed over the years to solve these problems. U.S. 2006/0218692 to Lamarque (publ October 2006), for example, teaches positioning of thermal transfer elements, vibrators, magnets, and a host of other therapeutic components within the cavities of pockets located about a jacket or other garment. Others place thermal pads in pockets of scarves (see U.S. Pat. No. 5,086,629 to Dibrell, February 1992) and cuffs for various parts of the body (see U.S. Pat. No. 4,985,924 to Perry, January 1991, and U.S. Pat. No. 4,625,729 to Roney, December 1986). These and all other extrinsic materials discussed herein are incorporated by reference in their entirety. Where a definition or use of a term in an incorporated reference is inconsistent or contrary to the definition of that term provided herein, the definition of that term provided herein applies and the definition of that term in the reference does not apply.
It turns out that using pockets to position thermal pads, however, is not an especially good solution. Among other things, the location of the thermal transfer element is predetermined by the location of the pockets. U.S. Pat. No. 5,887,437 to Maxim, March 1999 tries to solve that problem by adhering a thermal transfer element directly to the skin. But of course devices using that concept can be extremely uncomfortable.
U.S. 2006/0213156 to Nilfuroshan, (publ. September 2006) teaches a horse blanket, the underside of which has a hook-and-loop attachable material that releasably couples mating material on one or more pockets. The pockets (referred to as cavities) are sized and dimensioned to receive thermal transfer elements, and by moving around the pockets a user can position the thermal transfer elements substantially anywhere on the underside of the blanket. In that application, the concept was directed to non-human animals, which presumably would tolerate a blanket with a plurality of pockets facing the skin.
What is still needed is a method of expanding the horse blanket concept to human clothing, so that a user could position thermal transfer elements around the body, without having a plurality of pockets facing the bare skin of the wearer.
SUMMARY OF THE INVENTIONThe present invention provides apparatus, systems and methods in which an item of human clothing has inner and outer flexible layers that define a space sufficiently large to position a thermal transfer element in any of multiple, non-overlapping positions.
In preferred embodiments the space and the thermal transfer element have cooperating sides of a hook-and-loop attachment. For example, the inner surface of the outer layer can include a knit or woven fabric, or a napped or looped material, and a facing side of the thermal transfer element (or its housing) can include a hooked material.
All suitable items of clothing are contemplated, but especially a shirt, jacket or pants that appear to others as a substantially normal garment. Athletic jackets, “sweats” and other sporting- related garments are especially contemplated, with the inner and outer layers comprising cotton, nylon, or other fabrics known to the industry, including performance fabrics.
Each space has one or more openings, in either the inner or outer layers, and preferably at the shoulders or sides of the torso, or at the pocket areas of pants. The openings can be merely slits, or can have a suitable closure, for example a flap or a zipper.
The spaces are preferably large, not only relative to the size of a corresponding thermal transfer element, but also to the size of the garment. For example, a shirt or jacket can have a space extending across the entire upper or lower back regions, or along the entire left and right front panels. Contemplated spaces can alternatively extend across the entire back or front (for pullovers) or even a single contiguous space across the entire back and front. From a numerical perspective, a wall of a space having a hook-and-loop attachment material can advantageously have an area of at least 200-1000 cm2. Similarly, preferred clothing can be adjusted so that a space has a volume of at least 1000-8000 cm3. These and all other ranges specified herein should be construed as inclusive of their endpoints.
Thermal transfer elements can have any suitable configuration, and can be enclosed or otherwise coupled to any sort of holder. For example, a thermal transfer element can consist of a single gel pack, or multiple gel packs coupled at flex points. Alternatively, a thermal transfer element can include one or more plastic gel packs housed within a fabric covering. Most
There are many advantages to the various embodiments of the present invention. An advantage of one embodiment is the ability to adjustably secure a thermal transfer element to any body part covered by the garment. In this embodiment, the location of the thermal transfer element is adjustable over substantially an entire surface of an article of clothing because the fastener on the article of clothing is not fixed in a single location. Instead, in this embodiment, the fastener substantially covers an entire surface of the article of clothing. Thus a user of this embodiment of the present invention can precisely and adjustably target any body part covered by the article of clothing, instead of only specific, unchangeable locations.
Another advantage of an embodiment of the present invention is the ability to adjustably secure a thermal transfer element to an article of clothing multiple times without weakening the strength of the engagement between the fasteners. Other systems, which use adhesives to secure thermal transfer elements to an article of clothing, do not have this advantage because the adhesive weakens after every adhesion. Eventually, after multiple adhesions, the adhesive will no longer hold the thermal transfer element to the article of clothing. The engagement between fasteners of an embodiment of the present invention, however, does not so weaken due to repeated use.
Another advantage of an embodiment of the present invention is that it allows a person to apply a thermal transfer element to a hard to reach area, such as the back, without requiring the assistance of another. The person can simply secure the thermal transfer element to the back of the article of clothing before putting on the article of clothing. In other systems, it is very awkward or cumbersome to apply a thermal transfer element to the back without the assistance of another.
Another advantage of an embodiment of the present invention is that it allows a user to apply a thermal transfer element to a body part without occupying the hands. Thus, the user can engage in activities that require the use of one or both hands while a thermal transfer element is held against a body part. A further, related advantage is the ability to hold multiple thermal transfer elements, including both hot and cold thermal transfer elements simultaneously, to multiple body parts. Manual systems are limited by the number of thermal transfer elements the person can hold in the hands. The present invention, however, is not so limited.
A further related advantage of an embodiment of the present invention is the ability to engage in an athletic activity while a thermal transfer element is held against a body part. An athlete wearing a garment of the present invention is able to keep body parts warm during periods of inactivity, and need not remove the garment prior to resuming the athletic activity. Wearing the garment during the athletic activity can also prevent injury to muscles by keeping them warm. Alternatively, an athlete can cool parts of the body during strenuous activity to prevent overheating. Furthermore, a thermal transfer element secured to a body part can act as padding for that body part. Finally, after the athletic activity, the garment can be used for treatment of sore muscles.
Yet another advantage of an embodiment of the present invention is the ability to press a thermal transfer element against a body part. When the article of clothing snugly fits the body of the wearer, and when the thermal transfer element is secured inside the article of clothing, the snug fit presses the thermal transfer element against the body part. The term “snug fit” means that the article of clothing is tight on the wearer's body, having little or no slack in the material. The term “press,” as used in this context, means a force exerted on the thermal transfer element and toward the body of the wearer. This pressure increases the efficiency of heat transfer by increasing the surface area of the thermal transfer element in contact with the body part, because any gaps between the surface of the thermal transfer and the body part will be flattened out. Furthermore, pressure is also helpful for preventing swelling of an injured body part when a cold pack is applied.
These and other objects, features, aspects and advantages of the inventive subject matter will become more apparent from the following detailed description of preferred embodiments, along with the accompanying drawings in which like numerals represent like components.
An engagement between the first fastener 5A and the second fastener 5B removably and adjustably secures the thermal transfer element 4A to any location 6 on the interior surface 2 of the outer layer 11 of the article of clothing 1. Likewise, an engagement between a third fastener 5C of the second space 35 and a fourth fastener 5D removably and adjustably secures the thermal transfer element 4B to any location 6 on the interior surface 2 of the outer layer 11 of the article of clothing 1. “Removably and adjustably” secured means that the thermal transfer element can be removed without damaging the fasteners or otherwise dismantling the garment, and can be reattached in a different location. After attachment, heat transfer takes place between the thermal transfer element 4 and a body part 7 in contact with the location 6 on the article of clothing 1 where the thermal transfer element 4 is secured. The location 6 is “in contact” with the body part 7 even if there are one or more layers of material between the location 6 and the body part 7. In other words, it is not necessary for the location 6 to touch the skin of the body part 7 for the location 6 to “contact” the body part 7, so long as they immediately adjoin each other.

In an exemplary embodiment, as best illustrated in
The article of clothing 1 can be made from any flexible material. More specifically, and without limitation, the material can be moisture absorbent, breathable, stretchable, meshed, or any blend or combination thereof Even more particularly, the material can be a blend of nylon, polyester, and spandex. The material can also be thermoconductive in order to better conduct heat between the thermal transfer element 4 and the body part 7, or thermoreflective to help keep heat inside the article of clothing 1. The material can further comprise either the first fastener 5A or the second fastener 5B, meaning that these fasteners can be either an integral part of the material or affixed thereto. For example, one or more surfaces of the article of clothing 1 can be brushed such that it comprises loop material suitable for a hook and loop fastener.
The article of clothing 1 can be of any type including, without limitation, shirts, vests, shorts, pants, bodysuits, skirts, dresses, robes, and so forth, provided they can be configured to include a sufficiently large space for receiving the thermal transfer elements. From a numerical perspective, a wall of a space having a hook-and-loop attachment material can advantageously have an area of at least 200 cm2, 400 cm2, 600 cm2, 800 cm2 or even 1000 cm2. Similarly, preferred clothing can be adjusted so that a space has a volume of at least 1000 cm3, 2000 cm3, 4000 cm3, 6000 cm3, or even 8000 cm3. The jacket of

The thermal transfer element 9 is any object suitable for transferring heat including, without limitation, heat packs and cold packs of the type commonly used as hot or cold compresses on injured or sore body parts, whether single-use or reusable. The thermal transfer element 9 can contain water, ice, metal, gel, or any other material, whether solid, liquid, or gas. Examples of some types of thermal transfer elements include, without limitation, the Hot & Cold Flexible Gel Pack (3M, St. Paul, Minn.), Thermo-Pad Heat Packs (Hood Thermo-Pad, Summerlend, BC Canada), and the Hot/Cold Reusable Gel Pack (Accu-Therm, Taipei, Taiwan). The thermal transfer element 9 is brought to a desired temperature prior to attachment of the thermal transfer element 4 to the article of clothing 1 or, if possible, while the thermal transfer element 4 is attached. The thermal transfer element 9 can be heated or cooled in any suitable manner, including without limitation, convection, conduction, radiation, electrical resistance, and chemical reaction. For example, the thermal transfer element 9 can be cooled in a refrigerator, freezer, ice water bath, or endothermic chemical reaction. The thermal transfer element 9 can be heated, for example, in an oven, microwave, hot water bath, or exothermic chemical reaction.

Furthermore, the above steps can be repeated in any order to attach a plurality of thermal transfer elements 9 to a plurality of locations 6 contacting a plurality of body parts 7.
It should be understood that various alternative embodiments, not illustrated herein, are covered by the scope of the appended claims. For example, in one alternative the thermal transfer element can be adjustably secured to the exterior surface of the first layer, inside an outer layer. In this embodiment, the exterior surface of the first layer can be a brushed material suitable for use as loop material in a hook and loop fastener.
In another alternative embodiment of the present invention, the thermal transfer element can be adjustably secured to the interior surface of the first layer, whether or not there is also an outer layer. In this embodiment, the interior surface of the first layer can be a brushed material suitable for use as loop material in a hook and loop fastener.
In other alternative embodiments, the first fastener 5A and the second fastener 5B can be various different types of complementary fasteners other than hook and loop fasteners. For example, the fasteners can be metal or plastic snaps, hooks that engage with rivets, pairs of zipper chains engaged by a zipper, a button and buttonhole, or the like.
It should be apparent to those skilled in the art that many more modifications besides those already described are possible without departing from the inventive concepts herein. The inventive subject matter, therefore, is not to be restricted except in the spirit of the appended claims. Moreover, in interpreting both the specification and the claims, all terms should be interpreted in the broadest possible manner consistent with the context. In particular, the terms “comprises” and “comprising” should be interpreted as referring to elements, components, or steps in a non-exclusive manner, indicating that the referenced elements, components, or steps can be present, or utilized, or combined with other elements, components, or steps that are not expressly referenced. Where the specification claims refers to at least one of something selected from the group consisting of A, B, C . . . and N, the text should be interpreted as requiring only one element from the group, not A plus N, or B plus N, etc.
